Surface treating conditioning composition

The invention discloses a consumer product composition comprises a non-porous dissolvable solid structure comprising a carrier material having a viscosity at 70C, and a hydrophobic conditioning agent having a viscosity at 70C. The hydrophobic conditioning agent is disposed within the carrier material of the non-porous dissolvable solid structure. A ratio of the viscosity of the hydrophobic conditioning agent at 70C to the viscosity of the carrier material at 70C is from about 1000:1 to about 1:1000.
